Add version to BaseBiosTable to prevent data loss

The initial version of the Base BIOS table did not support Value Display
Names (VDN). Support for VDN was introduced in a commit [1]. A BMC image
created without VDN support stores data in the old BaseBiosTable format.
If a new BMC image (with VDN support) is flashed over an older image
(without VDN support), the BIOS manager attempts to read the binary
archive generated by the older BIOS settings manager. Since it doesn't
recognize the newly added property, it assumes the persisted file is
corrupted and ignores all the saved settings.

To prevent the loss of persisted BIOS data, the versioning support
provided by the Cereal library is used. This version information is
utilized to convert the persisted data into the current supported
format.

Add an optional argument to the daemon to allow the persistent
location to be a non-standard path. This enables running the
application as a normal user on a developer system rather than
requiring it to be installed in a full BMC image.

Fix the String type of pendingAttributes method

When the user calls the `pendingAttributes` method, if the
`attributeType` is equal to the string type, there is a chance that
the previous logic will fail because of the `std::get<1>` exception.

Since the string type has joined `MinStringLength` and
`MaxStringLength`, it is necessary to verify the maximum length and
minimum length of the string.
